1o core B sinks so that the frame A js lowered below the horizontal orintermediate position between the main and derived circuit coils, thebrake-lever is brought into contact with the stop H, and by a slidingmovement produced 1 5 by the brakeF turning in a-circle around the pointb the lever R is slowly elevated,v`and the I brake disengaged from itsgrip onthe brake-` wheel, thus permitting the carbon-holder to slightlydescend. .As soon as the carbon has zo fed t-o the proper point, themain coil pulls the core up again, and the brake drops onto the4brake-wheel, stopping its motion instantly.

The more quickly-it falls, or the more quickly the brake-wheel turns,the more quickly and 25 powerfully will the brake wedge itself againstthe brake-wheel.

By the construction above described thelam p may be made very.simplywith few parts. The lamp may also be made very strong and 3o at smallexpense. y a What -I claimvas my invention is .1. The combination, in anelectric-arc lam p, of a carbon or carbon-carrier, a wheel-work mountedon a pivoted frame or lever, a brake- 35 wheel gearing with thewheel-work and also mounted von said frame or lever, a pivotedbrake-lever sup orted from the frame and normally engaging .with thebrakc-whcel, and a fixed stop for acting upon the brake-lever. 4o 2 Thecombination, with the arc lamp brake-wheel mounted on the pivotedframe,of 'the pivoted brake-lever mount-ed on an arm or arms extendingdownward from said frame, and` a releasing stop arranged with relationto the case in the Patent Oiiice.
